H by endless chain H. shaft H is located at the rear end of the frame G and works within bearing-boxes b, fas-'" ro'tened to the frame.

The motion of the shaft G i is thus transmitted to the shaft H.- Tothe ceiling-beam H or in any manner, above the frame G, is attached the depending hangers d,

the endless can-elevator chain H which travels over sprocket-wheel d, secured to the shaft H, and

the shaft 02 To the endless can-elevator '20 chain is connected or secured a series of outwardly-projectinfg curved can-holding plates I, which receive the cans as delivered from the can -soldering machine and hold the same while being carried upward by the travel of the endless can -elevat0r chain.

The cans raised by the endless can-elevator chain as carried over the sprocket-wheel d? drop into the returnrunway or chute K, the

upper end K of which curves (over the shaft 0 d and is fastened to the rods fibolted to and depending from the beam H This runway or chute leads from the upper end of the endless can-elevator to the forward or feed end of the thereto by straps f the curved guard-plate K which prevents the cans from rolling off of the runway or chute whenthe lower end thereof is reached.

To the top of the solder' and flux holding receptacles or troughs is. secured the central strip or plate K, which divides the said receptacles or troughs and supports the ends of the cans as carried through the flux'and solthe endof the 5 der baths. 1

Connection is made between can-runway L and the soldering-machine by the strips or rods 5 6 7, which strips or rods are run at a gradual downward incline and are arranged at such an angle to each other as to throw or tilt the can L, which leaves the runway in a horizontal position, and deliver the same to the soldering-machine in an inclined position. As the can is fed into the soldering-machine it is engaged by the endless chain D hold the can in position. The movement of the endless chain 1) rotates the can first through thefiux-bath L and then through the solder-bath L machine only the lower edge of the can dips into the flux and solder baths, the body ofthe can resting against the edge of the frame A and the bottom thereof against the edge Fig. 5. Men the can reaches the opposite or delivery end of the machine, one end will be G". To the shaft G is which support the shaft 01 15 This shaft is connected with the. shaft H by.

'The' canwith the-soldered end as discharged from Q the solderingmachine rolls over the inclined rods 8 9.10, which lead'tothe bel'tG These rods are arranged at such an angle to each other that the can is placed upon the endless belt G in a vertical position with its freshlysoldered end uppermost. As the can is moved toward the endless 'can-"elevatorby the travel of the endless beltG th'e solder is allowed to cool or harden. Between the endless can-ele-' belt G is interposed the downwardly-inclined rod h. This rod, in connection with the deflector rod or plate h, serves to force the can from an upright or vertical position into a ig. 1', so as to place the can in position to be receivedby one ofthe canplates I, secured to the endless can-elevator. The deflector plate or rod h is run at an angle to the face of the endless belt G so that the upsetting of the can will be gradual. After the can is received upon the can-plate I it is. carried upward by the endless can-e vator and discharged at its upper end into t e runway K as the endless can-elevator moves over the sprocket wheel (i When the can is dropped from the'said elevator into the runway K, it rolls downwardly by gravity toward. the feed endof the machine dered or open end toward the solder-bath. the can-runway guard K I vator H and the discharge end of the endless I with its unso1- is connected to thesoldering-m'achine by the downwardly-inclined rods or straps 11 12 13, Fig. 4; 3 These rods are arranged at an angle to each other, similar to the rods 5 6 7, so as tothrow the can from a horizontal into an in clined position in order that it may roll through the flux-bath L and solder-bath L with only its unsoldered edge dipping therein. The can is carried through the flux and solder bath a second time by the travel of the endless chain D the body of the can resting -edge k of the frame A, and the lower end thereof against the edge of the central strip or plate K Fig. 5. As the can leaves the solder-bath it rides upon the downwardly-inclined rods 14 15 16 until it reaches the. discharge-belt G These downwardlyinclined rods are arranged at such an angle. to each other, similar to the rods 8 910, that the can rolling thereover is gradually thrown from an inclined to a vertical position, in which position it is placed upon the dischargebelt G with'its freshly-soldered end upper- As carried by this belt the solder is permitted to cool before the can reaches the discharge end thereof. The can as dropped from the discharge-belt is received into a runway (not shown) located within the frame G, which conveys the soldered can to any suitable place.
